Australian Sally Pearson (12.35 seconds, Olympic record) edged Harper (personal best 12.37 seconds) at the finish for the gold. Both athletes had to wait a few minutes before learning the official results. American Kellie Wells took the bronze.

Harper won the gold in the 100-meter hurdles in Beijing four years ago.

“Relax. Think about yourself. Stay focused,” Harper told herself ahead of Tuesday’s competition. “You know what you want to come out and do. I really feel the maturity. I can’t believe that I have this sense of peace right now. It’s crazy.” Harper spoke to the Associated Press.

Also on Tuesday, Chicago-native Wallace Spearmon competes in the first round of the Men’s 200-meter, which also features world-record holder Usain Bolt from Jamaica. Bolt, who has been dubbed “World’s Fastest Man,” won the gold in the 200-meter in 2008. Spearmon finished third in Beijing but was disqualified for stepping out of his lane. Christophe Lemaitre of France is another competitor in the 200-meter. Jamaica’s Yohan Blake is also a favorite.

Spearmon, along with Bolt, qualified for the semifinals during prelims on Tuesday morning. The semifinal is Wednesday and the final is Friday.
